Paramount removed all the Star Trek movies from their own streaming service, and gave them to HBO MAX. They have always billed their streaming service as "All things trek", but now they don't allow you to stream their own properties on their own streaming service.
I pay the higher rate for "ad free", but now I see ads before starting programs. Quite irritating. I assume if I read the fine print, I'll find that "ad free" changed at some point along the line to "fuck you, we're showing ads and you'll like it".
We also have numerous issues with the Paramount+ app on our FireTV - frequent crashes, trouble starting playback, and other things. It's by far the buggiest app we use.
I grew up with ads on TV and I stopped watching TV when I grew older. We have cable subscription now as a package for our internet, but it is not even connected. I own a TV but I only stream.
I cut the cord so I wouldn't have to watch commercials and there is no way in hell I am ever going back to them. And if they start having ads on all the services, I guess there will be a lot more piracy.
If you finish the UK show and want more, the same people behind it made a comedy fantasy show called Yonderland. It has most of the same cast (although some of them are just doing voices because there are puppets).
